Frog can detect earthquake

In 2009, the number of frogs in L'Aquila, Italy disappeared from the local pools, three days before the big quake.

Ms. Grant, a biologist from the Open University, observed the colony of frogs in L'Aquila as part of his research.

"It's very dramatic," he said. "96 frogs disappear within three days. After that I was contacted by NASA, "he added.

Together scientists from the U.S. space agency, they studied the chemical changes that occur when rocks in the earth experienced a big tekakan. They also were investigating whether the change is related to the mass exodus of frogs.

According to experts, geophysics, Friedemann Freund, said the rocks in the earth's crust is under great pressure, removing the particles. Particles released in the air when it reaches Earth's surface into the air molecules called ions.

These chemical changes can affect the dissolved organic matter in the water and makes the material is toxic to animals that live in water. That is the cause of animals such as frogs can detect strange changes that occur in nature.

The mechanism is complex and scientists say the process needs to be examined more carefully.

In line with Freund, the hypothesis the researchers (in a report published in the International Journal of Environmental Research and Public Health) said that the rocks in the crust of the Earth issued a charged particle, before the earthquake and this affects the water.

Scientists estimate that frogs can detect these changes before the tectonic plates shifted. Dr. Freund said the attitude of these animals can be one of a number of things that can be used as evidence of the earthquake.

"Once we understand all these signals and see there are four or five clues that lead to the same thing, then we can expect something to happen," says Dr. Freund, as quoted by the BBC Nature.

Animals are more sensitive to symptoms that occur in nature. We as humans still have much to learn in nature. This is evidence of how great God's creation, is not it?

The world's largest snake (Titanoboa)

Some scientists in Colombia have found fossils of a prehistoric monster believed to be the world's largest snake that ever lived on earth. The snake, named Titanoboa cerrejonensis was estimated to weigh over 1 ton and up to nearly 14 feet long.

The world's largest snake 0855525p (Titanoboa)

Some scientists believe this snake lived on earth some 58 million to 60 million years ago. Geologist David Polly, who estimated the size and weight of Titanoboa fossil based position.

"The size of the snake was quite big. However, the research team is still thinking about how much heat is required to warm the earth snakes of that size. "

Titanoboa fossil was discovered by a team of international scientists in a coal mine in the tropics Cerrejon, Colombia. "Snakes are very big this really invites the imagination, but the fact that there has been exceeded in Hollywood fantasy though," said paleontologist Jonathan Bloch, who is also involved in the expedition.

"The snake that tried to annex Jennifer Lopez in the movie Anaconda is not as big snake that we found," said Bloch. Based on the size of the snake, Bloch explains, scientists can calculate the average annual temperature at the equator in South America 60 million years ago to around 33 degrees Celsius, about 10 degrees warmer than today.

"Tropical ecosystems of Latin America today is much different than 60 million years ago," said Bloch. "The condition of tropical forests is almost the same as today, but the temperature is hotter then and filled with cold-blooded reptiles is greater."

According to Nature.com, snakes are poikilotherms animal species (cold blooded), which requires the heat of their neighborhood creeps to raise metabolism. Therefore, scientists estimate that the giant snake living in the tropical ecosystems of South America with temperatures was not under 30 to 34 degrees centigrade.

Most of the current population of snakes found in tropical South America and Southeast Asia. Temperatures in South America and southeast Asia enables the animal to grow until reaching a large size.

The collection of Unique Species Found In 2010

Every year new animal species discovered. Many of them have a unique characteristic and not encountered before.

In 2010, some interesting species found by scientists. Anyone can glow like a lamp, there is a devouring iron, some are able to produce materials that are stronger than kevlar. Here are a unique species in 2010 which have been collected by the website LiveScience.

1. Fish Pancake Batfish

This is a species of fish affected by the catastrophic oil spill in the Gulf of Mexico last year. Bears the Latin name Halieutichthys intermedius, these fish live in deep water areas.

With a flat shape like a pancake, this fish has a peculiar motion. More like a jump with fins along the bottom of the sea, rather than swim.

2. Spiders Darwin's Bark Spider

These animals come from Madagascar, and named Caerostris darwini. The spider is famous for its homemade nets are so big and long and strong. Spider webs can span up to 25 meters.

One example, he can stretch over a river in Madagascar by more than 30 insects trapped in the net. Not only long, but the cobwebs are also two times more potent than other spider webs and 10 times stronger than kevlar material the same size.

3. bacteria Titanic

This is a bacteria found by scientists from Dalhousie University in Canada and the University of Sevilla Spain on the wreck of RMS Titanic.

Bacteria with the Latin name Halomonas titanicae it consumes iron and steel, was found embedded in the surface remains of the Titanic which sank in the Atlantic Ocean.

4. Sierra Madre lizard

Commonly called golden leopard lizard or iguana Sierra Madre Forest, a giant lizard is found in the forests of Sierra Madre in the Philippines island of Luzon.

Monitor lizard Varanus bitatawa's Latin name, weighs about 10 kg and a length of about 2 meters, and the daily spend time in trees and eating fruit.

5. leeches Tiran

Leeches are found in Peru, the lining of the nasal cavity of a person. Has a length of 5 cm, blood-sucking animal has a single jaw and large teeth.

He called Tyrannobdella rex (meaning king tyrant leech). At least now there are 700 species of leeches that have been studied. It is estimated there are more than 10 thousand species of leech in the world.

6. Underwater mushrooms

Scientists discover new species of fungus that can live under water. Fungus named Psathyrella aquatica living in the Rogue River Oregon River United States. Miraculously, this mushroom has gills and can bear fruit in the water.

7. bioluminescent fungi

These glowing mushrooms found in the Atlantic forest habitat and collected in Sao Paulo Brazil. This little mushroom is less than 8 mm in diameter with a cap diameter that is smaller than 2 cm.

It has a rod coated by the gel, and capable of casting light yellowish green. Professor of Biology from San Francisco State University who discovered this fungus, Dennis Desjardin named this species Mycena luxaeterna (eternal light).

It is estimated there are about 1.5 million species on earth. Only 71 of them which is a fungus that can berrcahaya.

Wonders, The existence of a Vegetarian Shark

Could it be that trauma can affect the choice of eating a shark? This fact. A shark named Florence in 2009 were injured by fishing hooks, and this female sharks have entered the operating table in order to heal.

The surgery went well, but the impact is really changing the nature of eating Florence. Since then, he did not want to eat meat and vegetables instead choose. Not surprisingly, this 6-foot-long shark was nicknamed vegetarian shark.

Nature, are a class of carnivorous sharks. Meat is still needed for the body of nutrients. Initially, the guards at the Birmingham National Sea Life Center difficulty feeding meat to Florence. He always refused the meat is given. Finally, the guards set the tactics. They put the fish behind the vegetables. Florence was again receiving the appropriate nutrition.

"We had to hide the pieces of fish on the sidelines of celery sticks, cucumber and squeeze on salad leaves so that Florence would eat it. And, be clever to hide it. Otherwise, he would not care about the food we give, "said curator Graham Burrows told itv.com

Drain Flow Could Cause Electric Eels

God is great power there, creating an eel that has electricity. Various kinds of creatures were created to have the advantages of each of the properties of natural and unnatural.

Several hundred species of fish have electricity-producing organs, but few are able to generate electric power is strong. Electricity-producing organs are shared by most fish is composed of nerve cells and muscle cells that have undergone significant changes.

Forms of electric organ that produces such a small disc called Elektrosit mucus, composed and fused at the top of the other parallel arrangement. In general, all facing the same direction as the dish containing 150 or 200 discs per order.

For example, the torpedo fish dish there are 140 to 1000 electricity in each column. At a very large torpedo fish, the total number of discs to half a million.

The working principle of electric disc is similar to the way batteries work. When the fish to rest, the muscles that are not connected yet active. But if it receives a message from the nerve, will soon be working in unison to remove electrical power.

At that time, the voltage of all electric plate or Elektrosit fused, so as to generate electric power to 220 volts in the fish torpedo or up to 650 volts in an electric eel.

In general, all species of freshwater fish produce only electric light, unless Sembilang electric and electric eels. Electric fish that live in the ocean has a stronger power, and dangerous, because sea water contains salt that makes him more resistant to electrical current. The position and shape of the electric organ will vary depending on the species.

Besides fish, armed with an electric charge potential, there are also other types of fish that produce low-voltage signal of 2 to 3 volts. If these fish do not use this kind of weak electrical signals to hunt or defend themselves, and then used for what?

These fish take advantage of these weak signals as sensory organs. God created the body's sensory system in these fish, which delivers and receives signals.

These fish produce an electric radiant in a special tool in its tail. Electricity is transmitted through thousands of pores on the back of this creature in the form of a signal that temporarily creates an electric field around it.

Any object in this field refracts, so these fish know the size, power flow and motion of objects. In the body of this fish, there are electrical sensors that continue to define this field as well as radar.

In short, this fish has a radar that transmits electrical signals and translate changes in the field caused by objects that block the signals around the body. When the complexity of radar used by humans are still being grown, wonderful creation in the fish's body as it will become clear.

Forms of electric eel's body is unique, almost 7/8 form part of her tail. At the tail there is little batteries of small plates are horizontal and vertical. Huge numbers, more than 5,000 pieces.

Small electrical voltage of each battery is not great, but if all the batteries are connected in rows (series), will be obtained voltage about 600 volts (compared with batteries are only 1.5 volts).

Tip of the tail acts as a positive pole of the battery and the head end acts as a negative pole. Electric eels can regulate the relationship between the small battery in his body was to get a small electrical voltage and the voltage of electricity.

For navigation, electric eels requires only a small electrical voltage. But when dealing with enemies or prey, electric eel will provide a voltage to the maximum extent possible through the head and tail attached to the body of an enemy or prey.

About 1 ampere of electrical current generated by high voltage electricity will flow and kill them. But other animals are not disturbed as they are not in direct contact with the tail and head of the eel.

Why Do Bats Hiding When The rain?

Several species of bats still able to fly in conditions of light drizzle. But when the heavy rains, they immediately seek shelter. New research published in the journal Biology Letters reveals the reason why bats do that.

Apparently, the bat should try harder to fly when the feathers and their wings are wet.

In a series of studies conducted in Costa Rica, researchers studied the behavior of Sowell bats (Carollia sowelli) short-tailed species of the family Phyllostomidae bats are commonly found around Mexico, Central America, to Panama as they fly in captivity are spacious.

Quoted from Science Now, researchers occasionally wet bats with tap water, sometimes to let the bats fly wet under heavy rain.

From the study it was revealed that bats use energy more than twice as large as they fly in wet conditions compared to when they fly in dry conditions.

Flying in rainy conditions did not differ. These eliminate the suspicion of a mechanical problem caused by raindrops falling on their wings or weight of water droplets on them.

According to researchers, wet bat, just like other mammals being wet, cold. For that, they need to work harder to keep their bodies warm.

In addition, the amount of water and moisten the wet feathers of their wings, wet conditions is also of course make the bats become aerodynamic to fly.

The Capable Worm Found Living In the depth of 900 Meters

The Capable Worm Found Living In the depth of 900 MetersTullis Onstott, from Princeton University scientists, with colleagues from South Africa, Belgium and the Netherlands found a new species of worm called Halicephalobus Mephisto. Scientists found this worm lives in the depths of 900-3600 meters in the underground water layer on a gold mine in South Africa.

Onstott said he was surprised and did not think finding a worm in that depth. "Scary as hell when I first saw the worm moves. Worms that look like small black objects moving in circles, "Onstott said as quoted Dailymail.

Previously, many scientists thought that only the microorganisms that can live at that depth. Why, oxygen and nutrients are limited, and temperature extremes. However, the present invention, Onstott prove that multicellular organisms can survive in that environment.

In its publication in the journal Nature on Wednesday (06.01.11), Onstott explained that Halicephalobus Mephisto entered in the phylum Nematoda.

It has a small size, about 0.55 mm and can tolerate temperatures up to over 48 degrees celsius. Way is to reproduce asexually (without mating) and choose the food bacteria below the surface.

Carbon analysis showed that the water in the layer where the worm species found 3000-12000 years old. Believed that the species of worm that lives on the surface initially, but was taken to the lower layer by rainwater past. This worm is similar to fruit rot and worms that may have a kinship with him.

These findings could indicate that the underground environment is more complex than expected. The discovery of multicellular creatures also provide important implications for living underground search on other planets in the Solar System.

In addition to finding Halicephalobus Mephisto, Onstott and his colleagues also discovered other worms, including Plectus aquatilis.

Mammoth there is a blonde and want to be cloned

There are unique from the latest discovery of fossils of mammoths in Siberia. In addition to his body is still preserved intact, ancient animals that live in the ice age has blond hair slightly pink (strawberry blonde).
Yuka, the name of the juvenile mammoth fossil, discovered in a cliff frozen in Siberia, according to scientists, Yuka provide important insight into the secrets of animal shaped like a giant elephant that has not been known, such as hair and eye color.
Scientists who examined the body Yuka discover many mysteries. Body fossils, for example, shows early humans allegedly stole the rest of the carcass after death Yuka lion predation. It is known from injuries consistent with the mammoth body is strongly suspected in the attack and singa.Jika human right, the findings will be the first evidence of interaction between the mammoth and ancient human ever found in the area tersebut.Yuka estimated three to four years old when he died and still have the foot pads and the hair that grows between them. Scientists estimate Yuka buried in ice for more than 10 thousand years. Yuka's body following an injury suffered in a well preserved es.Kevin Campbell, professor of environmental physiology and evolution at the University of Manitoba, Canada, said the most striking thing about Yuka is a strawberry-blond hair.

"Mammoth-mammoth previously had darker hair. There was a possibility of mammoth hair a lighter color in 2006 when the scientists analyzed the genes of the bone, "said Campbell.

He said that fossil findings Yuka will help experts determine the presence of eye and hair color variation among populations of mammoths.
Daniel Fisher, professor of earth and environmental sciences at the University of Michigan, United States, said there is dramatic evidence of a life and death struggle between Yuka and a top predator. "Even more interesting, there is evidence that early humans might take over the murder of Yuka," said dia.Yuka ivory hunters first discovered in Siberia. The fossil was later taken over by Mammuthus organization, allowing the experts to begin to analyze it.
Intention of raising Mammoth
Campbell has also published a giant elephant hemoglobin genetic code is a few years ago. "It is rare to find specimens that are still incomplete as the discovery of a baby mammoth Lyuba in 2007. Surely this would be a boon for researchers, because it will help them connect the morphological traits that we can see with the genotype (DNA sequence). "Such information could help reveal whether the mammoth had all the same color hair as manusia.In fact, reportedly no intention to revive it through the process of cloning mammoths.
Campbell himself seems to support that goal, saying "maybe we can make important new discoveries in biotechnology."
Bernard Buigues of the scientific organization "Mammuthus" was revealed, "I will not oppose if there be a mammoth that lived in the (a) park of the future."

Tim Walker, producer and director of a show at the BBC told Discovery News that cloning a mammoth can take many tahun.Kemudian, if it happens, if later mammoth that life is not lonely?
"Yes, it's mammoth communal animals," said Walker.

Well, then later Jurassic Park would be true, then?

VFTS 682, Lonely Star At Magellanic Cloud

Using the Very Large Telescope (VLT) in Chile, astronomers have found a star named in the Tarantula Nebula VFTS 682, the Large Magellanic Cloud, a small neighboring galaxy to our Milky Way galaxy.

Star is more versatile than the Sun, has a mass 150 times greater than the Sun and 3 million times more luminous than the Sun.

However, unlike 682 VFTS star size and are typically found in dense star clusters. VFTS 682 which is one of the brightest star ever discovered and has a surface temperature of up to 50,000 degrees Celsius was apparently a lonely star.

As quoted Astronomy Now, Joachim Bestenlehner of Armagh Observatory in Northern Ireland who led the study, said, "We were very surprised to find that the star of that size alone was not located in a dense star cluster." Up to now, according to Bestenlehner, the origin of stars it remains a mystery.

Because of the location adjacent to the Tarantula Nebula and star forming regions close to the group VFTS R136 682, then astronomers suspect that the first 682 VFTS not alone. According to astronomers, VFTS 682 may be formed in the R136 cluster, and then flew out to exist in isolation.

The explanation may be the answer to puzzle 682 VFTS origin. But, if that were true, one more question arise. What kind of energy that could catapult for VFTS 682 stars from gugusnya?

To be sure, these findings will challenge the understanding of massive stars is growing now. The findings were published in the journal Astronomy & Astrophysics.

Most difficult of animals killed

Tropical Fish Mangrove Rivulus 800px to itself on the ground
RESEARCH U.S. scientists said the tropical fish that live in the swamps were able to survive for months without water. One type is the mangrove Rivulus fish (Rivulus marmoratus) that live in swamps berbakau throughout the Americas.

Once a bad season arrives and the water shrink, not rare fish that can only grow to the size of 7.5 cm was stuck in a tree cavity made of insects, shells, and even tin cans. They live huddled in a hole the ground and breathe using gills than the skin.

Unlike most fish breathe with gills, mangrove Rivulus skin breathe. When the habitat begins to dry, they hide in the soil pits, coconut shells or even canned beverages. In hiding, the fish skin to breathe and can live for months without water. After the rains came and water re-flooded habitat, they come out of hiding and live like ordinary fish.

Scott Taylor, a researcher of the Environment Endangered Land Program Brevard area in Florida, USA, without knowing accidentally while doing research in Belize, Central America. The actual type of tropical fish can also be found in Brazil and the United States.

"We take apart a tree trunk and the fish come out of nowhere," said Taylor. Then the results of testing done in the laboratory showed the fish to survive up to more than 66 days without water and food. Surprisingly, the body's metabolic system remains functioning normally.

Numerous species of fish known to have the ability to survive without water and food but no one so far. Let's see, catfish that can crawl on land for hours. Lung fish in Australia, Africa, and South America can live without water but only during the period of dormancy (fasting in summer).

The ability of fish may provide clues to how animals began to grow in the ground water. Patricia Wright, a biologist from the University of Guelph, Canada, said the fish habitat is similar to the environmental conditions of millions of years ago when the animals begin to migrate from water to land.

Not only survive without water, mangrove Rivulus fish also has a bizarre sexual condition. Each fish has testicular and ovarian parthenogenetic alias so that it can perform independently with a mate to fertilize their own eggs inside the body. "He is probably the most stable fish, not only has sex odd but also does not have a standard life like other fish," said Taylor.
